[Sportsman7]

I use my Polaris sportsman 500 to plow in the winter and when I put it in reverse and give it some gas it wants to rip the handlebars out of my hands and pulls a lot to the left. Is this a result of running my 27" swamp lite tires or do I have an issue here? It only does it when it is in 4wd reverse (speedo button.):hmmm:

I would check to make sure power is getting to all 4 wheels. If one of the front wheels is not driving you wouldn't notice as much going forward, but in reverse it would be much more noticeable and could cause it to pull.

Sounds like it could be your front differential. Mine did this when the plastic sprague cage was cracked, but not yet completely broken.
